The internet was flooded with compilation footage of the president executing his power shake, a maneuver designed to throw the opposing shaker off balance by suddenly jerking the arm away from that person’s body.

Watch how Trump executes his signature move in this clip compiled by CNN:

While dominant shakers such as Trump surely enjoy the thrill of such a thing, the experience is less enjoyable for the shakee. This begs the question: Is there any way to defend oneself from such a master of the art of the handshake?

Robin Gieseler of the Relson Gracie Jiu-Jitsu Academy says “yes.” And the Ohio instructor has just released a helpful video tutorial on how to counteract any such aggressive shake. He warns, however, that you should only use the technique on regular ol’ power-hungry narcissists, not on the actual president (because that would be very, very illegal).
